IMPROVEMENT IN SAFETY-PAPERS.

Specilication forming part of Letters Patent No. 167,223, dated August31, 1875 yapplication filed July 8, 1875 To all-whom it may concern:

Be it known that I, GEO. W. CASILEAR, of Washington, in the county ofl/Vashington and District of Columbia, have invented certain new anduseful Improvements in Safety- Paper; and I do hereby declare thatV thefollowing is a full and exact description thereof, reference being hadto the accompanying drawings, making a part of this specification.

My invention relates to a novel means for preventing the alteration orre-use of revenue and postage stamps, or the raising or otherwisechanging the character or value of any evidence of value printed onpaper, or counterfeiting the same by transfer, photography,photolithography, &c.

With these objects in view, my invention consists in a paper of ordinarystructure or ingredients, with its top surface covered with a wovenfabric, or with a warp of fragile open texture and meshes, or the warpsecured to and embedded in the paper body or foundation during theprocess of manufacture of the paper, or afterward by uniting the twounder pressure; the natural moisture of the pulp in the manufactureofthe paper, or the dampening slightly of the sheet after manufacture,serving to sufficiently meisten and soften the starch or gluten in thetextile covering, or the sizing of the paper, to induce to a perfectunion of the fabric and paper when pressed and dried and calendered. Thepaper thus prepared with a textile-fabric face or upper surface may bereadily printed upon either by type or plate, and may also be writtenupon with a pen; and any effort made to erase any of the printing orwriting from the face of the paper by the use of a knife willnecessarily result in the destruction of the lace-work or fabriccovering, for the ink, being absorbed by the fibers of the fabric, canonly be thoroughly erased by completely cutting away such portions, andas the weft and Warp (or the warp, if preferable) give character to theface of the paper, the absence thereof at any particular place would bereadily recognized, and suspicion awakened, resulting in the certaindetection of any ei'ort at tampering. Another resulting benet from myinvention is the fact that by using colored textile fabrics a surfacetint77 may be given the paper without the the print fac-simile byphotography or photo-- lithography. It will also be impossible toextract the color, or transfer to a plate, or erase any ligure orevidence of value for any of the purposes of counterfeiting or altera-`tion by any liquid or acid treatment, for the reason that the surfacecovering of lace or other woven fabric or warp readily and quicklyabsorbs, by capillary attraction, any uid coming in contact with it, anddraws away from its paper foundation to a greater or less extent,according to the treatment it receives, but in every case to such anextent as to magnify and make patent any effort at erasure oralteration.

My invention is designed more particularly for internalrevenue andpostage stamps, checks, bonds, &c., though, of course, it may be used togreat advantage elsewhere; and for a full and more perfect descriptionof the advantages attending the use of my improved paper for revenuestamps, Snc., I refer to another application filed myself and WV. C.

Mclntire, jointly, for improved revenue and postage stamp.

In the drawing accompanying this specilication, Figure l represents alive-pound snuffstamp made orprinted upon ordinary paper in black, andFig. 2 represents a similar stamp printed upon paper embodying theelements of my invention, the broken lines crossing each other at rightangles representing a woven fabric of pink or other desirable color,secured in the manner hereinbefore described to the paper body, (thepaper and textile cover being both .exposed to view,) and afterwardprinted upon, the impression necessarily being partly on paper andpartly on spun fiber; and Fig. 3 is a cross-section, on an enlargedscale at m a: of Fig. 2, showing the woven or other fabric embedded inthe surface of the paper.

Having described my invention and its advantages so that those skilledmay make and use the same, and not wishing to be understood, asclaiming, broadly, a paper and woven fabric combined,

What I claim as new, and desire te' secure i View, and he capable ofseparation, in the by Letters Patent', is-
